  After implementing a similar autotest for shadow quads, I would rather prefer not do so because the integration test will become extremely difficult to work with and ugly. I think it's better for now to use test clients to verify that generated window quads are okay. However, it would be nice to have a test or two that verify rendered frames. Are there any projects or compositors that check pixel data in their test suites? I would really love to see how those projects organize their tests and how overall this approach looks in code.
